' CLAIRE N. BREWER, OF HUNTINGTON, WEST VIRGINIA ATTACHMENT FOB TYPOGRAPHICAL MACHINES Application filed November 9, 1928. Serial No. 318,242.

This invention relates to typographical machines and more particularly to the delivery slide assemblage.

One of the primary objects of this invention is to provide novel means for constructing the short finger of the delivery slide assemblage so as to permit movement of this finger'relative to its block to prevent damage to this finger should the assembler elevator mechanism be in the path thereof during the return of the delivery slide assemblage and to prevent injury to the hand of the operator of the machine incident to the removal of an incorrect matrix from the line of matrices being assembled.

During the assembling of a line of matrices an incorrect key is often struck by the operator of the machine which necessitates the removal of the incorrect matrix from the line. The operator usually reaches over to the first elevator to remove the incorrect matrix and being intent upon his work very often does not notice the position of the short finger of the delivery slide assemblage and the elevator. This results in. the hand or fingers of the operator being caught between the short finger and the elevator, causing painful injury. Further, itsometimes happens that the assembler elevator will be in the path of the short finger during th-e return of the delivery slide assemblage resulting in the breaking of and the throwing of the the short finger mechanism out of line.

It is therefore, a salient feature of the invention to provide novel means for connecting the short finger toits block, said means embodying a hinge joint allowing the swing ing of the finger away from the elevator in one direction but the holding of the finger rigidly against movement in the other direction thereby allowing the finger to swing away from the elevator, should the same be in the path of the elevator and away from the hand of the operator should the hand of the operator be caught between the finger and elevator, resilient means being providedfor normally holdingthe short finger in normal position.

A further object of the invention is to provide an improved short finger for the delivery slide assemblage, which can be readily associated with the delivery slide assemblage without change thereto or other operative parts of the machine. r

A still further object of the invention is to provide an improved short delivery slide finger of the above character for typographical'machines, which will be durable and efii cient in use, one that will be simple and easy to manufacture, and one that can be placed upon the market and incorporated with a standard typographical machine at a low cost.

Viththese and other objects in view,the

invention consists in the novel construction, arrangement andform'ationof parts, as will be hereinafter more specifically described, claimed, and illustrated in the accompanying drawing, in which drawing 7 I Figure 1 is a fragmentary front elevation of a typographical machine illustrating the delivery slide assemblage, the assembler elevator and associate parts. 7

Figure 2 is a perspective view showing the delivery slide short finger block with my improved short finger connected thereto.

a Figure 3 is a side elevation of the same.

Figure 4 is a vertical section through the finger and block taken on theline 44E of Figure 3, looking in the direction of the arrows. J v

Figure 5 is a vertical'section taken on the line 5-5 of Figure 3, looking in the direction of the arrows.

Referring to the drawing in detail, wherein similar reference characters designate corresponding parts throughout the several views, the letter A generally indicates a fragment of a standard typographical machine which includes the frame 10,the space band box assemblage 11 with the vertically movable assembler elevator 12 which receives the line of matrices duringthe assembling thereof. Arranged above the first elevator is the line delivery assemblage 13 which receives the assembled line from the elevator for delivering the same to the first elevator. This slide delivery assemblage 13 includes the back bar 14, the short finger 15 and its block 16, the long finger 17 and its block 18, and the delivery slide rod 19 which projects from the block 18 of the long finger through the block 16 of the short finger, the block having a bore 20 for the reception of this rod.

This assemblage functions in the usual manner and the standard parts will not be described in detail. As stated the short finger 15 and the long finger 17 are adapted to grasp and transfer the composed line after it has been lifted to the desired level by the assembling elevator 12. The fingers as in the usual construction have relative movement for grasping the composed line and for synchronous movement for carrying the composed line to the first elevator.

Referring more specifically to the short finger 15 and block 16 wherein my invention resides,.it can seen that the block includes the usual slide body 21 having the forwardly and laterally projecting arm 22 to which is usually integrally connected the short finger 15. V

In accordance with my invention the inner face of the laterally projecting arm 22 is provided with a recess 23 which opens out through the lower face of the arm. The lower face of the arm 22 in rear of the recess or notch 23 forms a stop shoulder 24, for a purpose which willbe later described. This arm 22 carries the usual latch plate 25 which can be secured thereto by the use of a suitable pin 26 and screw 27. This latch plate 25 formsno part of the present invention but it is to be noted that the lower edge thereof is flush with the shoulder 24. The latch plate 25 cooperates'with the release pawl in the ordinary way, and as stated, does not relate to the improved construction.

Myimproved short finger 15 i'ncludes'the upper body portion 28 and the depending relatively thin finger portion'29 and the upper end of the body portion 28' at one side thereof is provided witha hinge barrel 30 which is received in the notch or recess 23. A pivot pin 31 extends through the arm 22 and hinge barrel 30 for pivotally securing the finger 15 in position and it is tobe noted that the finger at one side of the hinge barrel 30 is provided. with a stop shoulder 32 which is adapted to engage theshoulder 24: on the finger and the lower'surface of the latch plate 25.

By this constructiom' so far, it can be seen that the finger 15 is allowed free swinging movement away from the space band box assemblage. andthe elevator 12 but is pre vented from swinging movement toward the said space band box assemblage.

In order to normally retain the short finger 15 in its operative vertical pos tion, provide a relatively Weak contractlle coil spring 83 which has its opposite terminals connected to pins 34 and 35 carried respectively by the arm 22 and the upper end of the finger 15 on one side of the pivot pin 31. WVhile this spring will function to normally hold the finger in its operative position, the spring will permit the finger to swing to one side when the same comes into engagement with a firm or rigid object.

In operation of my improved short finger, as stated,- the same functions in the usual way, but it can be seen that in case the operator strikes the wrong lrey and an incorrect matrix is delivered to the line being assembled in the elevator and the operator reaches to recover the incorrect matrix, and should the elevator 12 be in a'raised position and the short finger moving toward the spaceband box assemblage, the fingers of the operator are liable to be caught between the elevator and the short finger, the finger, however, will give and swing to one side and thus efieetively prevent injury to the fingers or hand of the operator. This materially lessens the hazards incident to the recovery ofincorrect matrices delivered to the line being assembled.

It also can be seen that in cases where the first eleva or is in its raised positioniand the short finger is moving toward the right (Figure 1 of the drawing) the short finger will be merely swung to one side thereby preventing the breaking thereof. This prevents not only the breaking of the short finger but also prevents the machine from being thrown out of line and consequently out of operation due to the injury of this finger. 7

Changes in details may be made without departing from the spirit or the scope of the invention, but: what I claim as'new is:

1. In typographical machine, a line transfer finger comprising a supporting slide-block having a laterally projecting arm membena finger proper member, one ofsaid members being provided with a recess and a stop shoulder at one side of said recess, and the other of said members having a' hinge barrel and a stop shoulderat oneside of the hinge barrel, the hinge barrel being received in said recess,- a pivot pin extending into the member having the recess and through the hinge barrel, the barrel permitting the swinging of the finger proper in one direction and the stop shoulders limiting the swinging movement of the finger proper in the opposite direction, and spring means normally holding the shoulders in contact.

2. In a typographical machine, a transfer finger comprising a supporting slide block havlng a laterally projecting arm provided with a recess on its lower faceon one side thereof and a stop shoulder on the other side, a finger proper including a hinge barrel on the upper end thereof adjacent to one edge mounted in said recess, a pivot pin extending into the arm and hinge barrel, the upper end of the finger proper on one side of the barrel forming a stop shoulder for engaging the stop shoulder of the arm whereby swinging movement of the finger in one direction is prevented, a relatively Weak contractile coil spring and means connecting the opposite terminals of the spring to the arm and finger proper on one side of the pivot thereof.

In testimony whereof I aflix my signature. CLAIRE N. BREWER.
